BER Display
Bit Error Rate (BER) Display is utilized by the operator to measure the amount bit errors present in
a link. BER Display will only work if the access point module is configured to send the BER stream.
**IMPORTANT** If one access point module in a cluster is set to send a BER stream then all
other access point modules in that cluster must be configured in the same fashion.
The field, Measured Bit Error Rate, will display a value that corresponds to the BER at the moment
of web browser refresh. An acceptable link will have a BER that is less than 10
-4 . If the BER is
greater than 10 -4 then the operator needs to evaluate the subscriber and/or access point module
installation for potential issues. To refresh the screen, click the Refresh Display button as
appropriate or configure the web page auto-refresh option.
